Question 4

Portability describes how well a system can scale up,or adapt to the increased demands of growth.

Accepted Answer

Scalability describes how well a system can scale up,or adapt to the increased demands of growth.If a company grows faster than anticipated,it might experience a variety of problems,from running out of storage space to taking more time to complete transactions.Anticipating expected,and unexpected,growth is key to building scalable systems that can support that development.

Question 5

Usability is how quickly a third-party or vendor can change a system to ensure it meets user needs and the terms of any contracts including agreed levels of reliability,maintainability or availability.

Accepted Answer

Accepted Answer

Capacity planning determines future environmental infrastructure requirements to ensure high-quality system performance.

Question 13

A system is called available when it is not operating and can't be used.

Accepted Answer

A system is called unavailable when it is not operating and can't be used.

Question 14

Unavailability occurs when a system is continuously operational at all times.

Accepted Answer

High availability occurs when a system is continuously operational at all times.
